A gas cylinder 50 is fixed in the first hollow rod 20, and liquid high-pressure carbon dioxide gas is stored in the gas cylinder 50. The volume of these gases after expansion is sufficient for the air cushion 10 to expand to be taut, and the gas cylinder 50 inflates the air cushion 10 through a gas delivery component.

[0025] Reference Figure 1 First, cut off the parts of the two TPU fabrics that are consistent with the cross-section of the drainage port 101, and then make the fabric of the same material as the air cushion 10 into a circular ring and glue it between the two TPU fabrics along the cut-off part, so that two drainage ports 101 are formed in the air cushion 10 and penetrate through its thickness, and the air cushion 10 is hollow.

[0026] Reference Figure 3 Two rod sleeves 22 are rotatably connected to the outer periphery of the first hollow rod 20 , and two connecting parts 12 covering the outer periphery of the rod sleeve 22 are fixed to the edge of the air cushion 10 close to one side of the first hollow rod 20 .

[0027] Reference Figure 2 A hook portion 211 which is recessed radially inward is provided on the outer periphery of the second hollow rod 21. A plurality of movable buckles 11 are fixed on the edge of the air cushion 10 close to the second hollow rod 21. The movable buckle 11 can be buckled in the hook portion 211. The inner diameter of the movable buckle 11 is smaller than the outer diameter of the second hollow rod 21. One end of the movable buckle 11 is bonded to the outer surface of the air cushion 10 by an adhesive.

[0028] Reference Figure 1 The connecting rod 30 is composed of a horizontal part located on the upper side of the air cushion 10 and a vertical part located on both sides of the air cushion 10. The ends of the vertical parts of the connecting rod 30 are fixed with buckles 31. The lower end of the buckle 31 is opened, and the opening size is smaller than the diameter of the second hollow rod 21 and the first hollow rod 20. The buckle 31 can be clamped on the outer periphery of the second hollow rod 21 and the first hollow rod 20.

[0029] Reference Figure 3 , Figure 4 , FIG. 10 , the gas delivery assembly includes a gas delivery pipe 40 and a connector 41, the connector 41 is rotatably connected to one end of the gas delivery pipe 40, the other end of the gas delivery pipe 40 is fixed to one end of the first hollow rod 20, a connecting pipe 51 is fixed between one end of the first hollow rod 20 to which the gas delivery pipe 40 is fixed and the end of the gas cylinder 50, the connecting pipe 51 connects the gas cylinder 50 and the gas delivery pipe 40.

[0030] Reference Figure 4 The air cushion 10 is fixed with an inflation port 13 connected to the interior thereof, and a one-way valve 14 is fixed in the inflation port 13. The one-way valve 14 is composed of a valve body 1406, a core rod 1404 and a pressure plate 1401. The valve body 1406 is fixed in the inflation port 13. A ventilation cavity 1405 is provided in the valve body 1406 along the axis direction of the inflation port 13. The ventilation cavity 1405 connects the interior of the air cushion 10 with the inflation port 13. The core rod 1404 penetrates the valve body 1406 along the axis direction of the valve body 1406 and is slidably connected thereto, sealing The blocking plate 1403 is fixed to one end of the core rod 1404 away from the connecting head 41. The blocking plate 1403 can block the ventilation cavity 1405. The pressure plate 1401 is fixed to the other end of the core rod 1404. A return spring 1402 is fixed between the pressure plate 1401 and the valve body 1406. An external thread is provided on the outer periphery of the inflation port 13, and an internal thread is provided on the inner side surface of the connecting head 41. The connecting head 41 is threadedly connected to the outer periphery of the inflation port 13, and one end of the air supply pipe 40 provided with the connecting head 41 can be inserted into the inflation port 13.

[0031] Reference Figure 4 A valve core 42 that can abut against the one-way valve 14 is fixed in one end of the air supply pipe 40 near the inflation port 13. The valve core 42 can abut against the pressure plate 1401. When the two abut against each other, the valve core 42 and the one-way valve 14 are both open. When the valve core 42 is pressed in a direction away from the pressure plate 1401, the valve core 42 is in an open state.

[0032] When conducting water rescue, the air cushion 10 is in a rolled-up state, and rescuers can take a rescue boat carrying the present invention to quickly rush to the person who falls into the water. When approaching the person who falls into the water, the air cushion 10 is pulled away from the first hollow rod 20 to fully unfold it, and at the same time, the two connecting rods 30 are buckled onto the first hollow rod 20 and the second hollow rod 21 through the buckles 31, and the first hollow rod 20 and the second hollow rod 21 are placed on both sides of the person who falls into the water, and the person who falls into the water can hold the connecting rods 30 with both hands.

[0033] At this time, the rescuer passes the air cushion 10 under the drowning person and buckles the movable buckle 11 on the second hollow rod 21 .

[0034] Then, the connecting head 41 is connected to the inflation port 13. During this process, the valve core 42 abuts against the pressure plate 1401. As the connecting head 41 continues to rotate, the valve core 42 continues to move toward the direction close to the one-way valve 14, thereby pressing the valve core 42. At the same time, the valve core 42 presses the pressure plate 1401 toward the air cushion 10, thereby connecting the ventilation cavity 1405 with the air cushion 10. At this time, the high-pressure carbon dioxide gas in the gas cylinder 50 is transported to the air cushion 10 through the gas pipe 40, thereby causing the air cushion 10 to expand rapidly, thereby floating the person who falls into the water on the water surface, so that the rescue personnel can carry him back by the rescue boat, thereby reducing the movement of the person who falls into the water and reducing the possibility of secondary injury.

[0035] After the rescue is completed, the connecting head 41 can be removed from the inflation port 13, and the pressure plate 1401 can be pressed to release the gas in the air cushion 10 to restore it to a flat shape. At the same time, high-pressure carbon dioxide gas can be re-injected into the gas storage bottle 50 through the gas pipe 40. After the connecting rod 30 is separated from the first hollow rod 20 and the second hollow rod 21, the air cushion 10 can be re-rolled onto the first hollow rod 20.

[0036] It will be clear to those skilled in the art that various modifications to the above embodiments may be made without departing from the overall spirit and concept of the present invention. All of these modifications fall within the scope of protection of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
